Spray Drying of Bacillus subtilis spores
Spray Drying of Bacillus subtilis spores with the Mini Spray Dryer B-290
Bacillus subtilis is a Gram-positive bacterium that produces durable and highly resistant spores. Spray drying has been explored as a technique for the production of Bacillus subtilis spore powders, offering advantages such as improved stability, ease of handling, and extended shelf life.
The areas of focus in spray drying of Bacillus subtilis spores include optimizing the process parameters, such as the inlet and outlet temperatures, atomizer type, and feed rate, to achieve the desired particle size, morphology, and viability of the spores. Additionally, research has been conducted to evaluate the impact of different drying conditions and formulation additives on the physical and biological properties of the powder, such as its survival rate, rehydration characteristics, and resistance to environmental stressors.
Furthermore, spray drying has been investigated as a method for producing Bacillus subtilis spore-based formulations, which can be used in various applications, including probiotics, biopesticides, and bioremediation agents. These spore powders offer enhanced stability and can be easily incorporated into various products or formulations, allowing for their effective deployment in different industries.
Overall, spray drying of Bacillus subtilis spores offers a promising approach for the production of stable and viable spore powders, enabling their use in a wide range of applications in agriculture, healthcare, and environmental management.
